Remittances and GDP in Jamaica: An ARDL Bounds Testing Approach to Cointegration

Similar to other developing nations, Jamaica’s remittances, specifically inflows, are an important source of income support and foreign exchange earnings. Anecdotally, much has been said about the relationship between remittances and GDP in this country. Yet, less has been established using rigorous statistical inference. We test for unit roots with structural breaks and use the autoregressive distributed lag (ARDL) approach to cointegration to help fill this lacuna in the literature on Jamaica. Using annual data for the 1976–2014 period, we examine the relationship between GDP and remittances, both measured in constant 2010 US dollar terms, as we control for the common determinants of economic growth. The main finding is that GDP and remittances are cointegrated relationship wherein they both reinforce each other positively. This finding is statistically robust as the ARDL models have well-behaved errors and parameters that are generally stable over the period. We discuss policy implications of this finding.     

Financial cycle and business cycle: An empirical analysis based on the data from the U.S

In this paper, we first study the relationship between the financial cycle and the business cycle in the time and frequency domain. Then we also explore the interactions and dynamic mechanisms of the financial cycle, the business cycle, real interest rate and exchange rate by the VAR model. The empirical results show that the financial cycle is closely related to the business cycle, especially at medium-term frequencies (8–30 years), the business cycle leads the financial cycle with a high positive correlation. However, the relationship between them is not significant during the Great Moderation at business-cycle (2–4 years). In addition, the financial cycle not only becomes a main driver of real interest rate, the financial cycle and the business cycle, but also serves as an important source of the business cycle fluctuations. In general, our results lay some theoretical foundation for the policy practice of financial and economic stability.     

Cointegration Approach to Estimating Bilateral Trade Elasticities Between U.S. and Her Trading Partners

Almost all previous authors who estimated the trade elasticities relied upon aggregate trade data. To avoid the aggregation bias, this paper provides estimates of trade elasticities using bilateral data between the United States and her six largest trading partners. Application of cointegration analysis reveals that in many cases, bilateral trade elasticities are large enough to justify real depreciation of the dollar as a mean of improving U.S. trade balance.[F14]     

A sneeze in the U.S., a cough in Japan,but pneumonia in Taiwan? An application of the Markov-Switching vector autoregressive model

This paper examines the lead–lag relationships among the output of Taiwan, Japan and the U.S. Three testing methods are employed: the traditional linear Granger causality test, Hiemstra and Jones' [Hiemstra, C., Jones, J.D., 1994. Testing for linear and nonlinear Granger causality in the stock price-volume relation. Journal of Finance 49, 1639–1664] nonlinear Granger causality test and Warne's [Warne, A., 2000. Causality and regime inference in a Markov-S switching VAR, Working Paper no. 118, Sveriges Riksbank, Stockholm.] Granger causality test under the Markov-Switching model. We find that the causal ordering is unclear and depends on the model we used. Because Markov-Switching model imposes few restrictions in estimation, we tend to use its estimated results but bear in mind that the evidence is sensitive. First, the common shock hypothesis is found that most probably exists between Taiwan and the U.S. Next, we conclude that Japan tends to lead Taiwan's output, to a certain extent. Last, there is no causal ordering between the U.S. and Japan economies.     

美国经济周期稳定化研究述评

近50年来美国经济周期出现了稳定化的趋势,其中二战之后经济周期的波动性比二战之前有明显下降,20世纪80年代中期之后比80年代之前亦有显著下降。引起这种经济周期稳定化的原因是多方面的,美国宏观经济学界对这一现象展开了热烈的讨论。本文对该领域的主要文献进行了梳理,对不同的观点进行了比较,并从美国的争论中得出了对中国有借鉴意义的启示。     

The expected inflation channel of government spending in the postwar U.S.

There exist sticky price models in which the output response to a government spending change can be large if the central bank is nonresponsive to inflation. According to this “expected inflation channel,” government spending drives up expected inflation, which in turn, reduces the real interest rate and leads to an increase in private consumption. This paper examines whether the channel was important in the post-WWII U.S., with particular attention to the 2009 Recovery Act period. First, we show that a model calibrated to have a large output multiplier requires a large response of expected inflation to a government spending shock. Next, we show that this large response is inconsistent with structural vector autoregression evidence from the Federal Reserve׳s passive policy period (1959–1979). Then, we study expected inflation measures during the Recovery Act period in conjunction with a panel of professional forecaster surveys, a cross-country comparison of bond yields and fiscal policy news announcements. We show that the expected inflation response was too small to engender a large output multiplier.

Quantile regression with sample selection: Estimating women's return to education in the U.S.

This study uses quantile regression techniques to analyze changes in the returns to education for women. The data used is the March Current Population Survey for the years 1968, 1973, 1979, 1986 and 1990. The first step in estimating the single (linear) index selection equation uses Ichimura's (1993) semiparametric procedure. To correct for an unknown form of a sample selection bias in the quantile regression, the second step incorporates a nonparametric method, using an idea similar to one developed by Heckman (1980) and Newey (1991) for mean regression, and Buchinsky (1998) for quantile regression.  The results show that: (a) the returns to education increased enormously for the younger cohorts, but very little for the older cohorts; (b) in general the returns are higher at the lower quantiles in the beginning of the sample period and higher at the higher quantiles by the end of the sample period; (c) there is a significant sample selection bias for all age groups at almost all quantiles; (d) toward the end of the sample period there is a significant convergence of the returns at the various quantiles, especially for the younger cohorts and age groups; and (e) the semiparametric estimates of the selection equation are considerably different from those obtained for a parametric probit model.     

The cyclical behaviour of prices in the U.K.: Some structural time series evidence

The cyclical behaviour of prices in the U.K. is investigated using a sample of annual observations covering the period 1886–1993. A structural time series model relating consumer prices to output is estimated over four sub-periods. The results indicate that prices were procyclical in the inter-war period, countercyclical in the post-1973 period and acyclical otherwise. The proposition that the cyclical behaviour of prices is determined by the dominance of supply or demand shocks alone is disputed on the basis of empirical evidence and theoretical reasoning. It is concluded that the cyclical behaviour of prices cannot be explained just by analysing time series on output and prices and that due attention should be paid to the institutional and policy changes occurring during the period under study. It is demonstrated that the empirical results are consistent with the events experienced by the U.K. economy in the most recent period.

Manufacturing Wage Differentials and Employment in Some Scandinavian Countries, the U.S. and the U.K.: An Analysis of Variance Approach

This paper presents some empirical evidence on the factors determining changes in wage differentials between skilled and unskilled workers and in their employment. An ``analysis of variance' (ANOVA) model is estimated using UN data for five OECD countries in order to assess the relative importance of industry-specific, country-specific and international shocks (as well as interactions between industry and country effects). It is found that both international shocks and national policies affect wage differentials over the whole sample, whilst skill-biased technical change (SBTC) was a significant factor in the seventies. Employment responds mainly to international shocks, although national policies and SBTC were important determinants in the seventies and eighties respectively. Some of the results are found to be sensitive to the technology level of the industries considered.     

Measuring the size and dynamics of U.S. state-level shadow economies using a dynamic general equilibrium model with trends

We use a two-sector dynamic deterministic general equilibrium model that specifically accounts for trends among time-series variables to estimate the size of the shadow economy for the 50 U.S. states from 1999 to 2019, following Solis-Garcia and Xie (2018, 2022). This paper improves on existing measures of the state-level shadow economy (such as the multiple indicators, multiple causes (MIMIC) methodology by Wiseman (2013a)). In particular, this new measure is based on theoretical foundations, extends the previous measure to include the Great Recession, includes dollar value estimates of the shadow economy, and produces considerably more variation over time and across states. Furthermore, we explore determinants of this new shadow economy measure using a panel vector autoregressive model and find that, on average, states with higher levels of economic freedom, lower regulatory barriers, and larger real GDP have smaller shadow economies. States with bigger governments, on average, have larger shadow economies, and the effect of corruption on shadow economic activity is non-linear, with a positive initial and subsequent negative impact.     

Methodological Extensions of First-Order Adjustment Models: An Application to U.S. Industries *

This paper empirically tests two industrial-organization models with a sample of 182 U.S. industries, from to 1963 to 1967. The models extend standard models and integrate them with dynamics associated with the " persistence of profits" methodologies. We extend it by replacing the traditional cross-section profit equation with a profit-adjustment equation for U.S. industrial data. Our study measures the speed of adjustment of profits and explicitly models steady-state profits, in addition to the speed of structural adjustment and steady-state market structure. We find that the structural-adjustment speed is slower than the profit-adjustment speed and that nonzero economic profits tend to be quite persistent     

Technological Change Bias In The U.S. Investor-Owned Electric Utility Industry Following Potential Deregulation

This paper estimates regulated and poientially deregulated costs of production for a multiproduct electric utility industry. The empirical evidence suggests technological regression with respect to costs in both regulated and deregulated environments. Analysis of factor cost shares indicates that technological change in a deregulated environment is expected to be less apital saving than technological change in the regulated environment. In addition, this study finds that overall diseconomies of scale may be nduced over time and to a greater extentunder deregulation than under regulation. Also, cost complementarities may be enhancedover time, but to a lesser extent under deregulation. Hence. tendencies toward natural monop oly may be increased or decreased by deregulation, and advancing deregulation may or may not be an appropriate policy.     

Equal Pay for Equal Work? Evidence from Sweden and a Comparison with Norway and the U.S.

Using a new data set covering most privately employed workers in Sweden, we compare gender wage differences to those previously reported for Norway and the U.S. The central finding is that the wage gap is small when comparing men and women working in the same type of occupation for the same employer. Segregation of men and women by occupation accounts for more of the gap in Sweden than in the other two countries. In all three countries, we find that segregation by occupation explains more than segregation by establishment, and that institutional changes over the past two decades aimed at improving the status of women had little effect on the gender wage gap.

An empirical investigation of herding in the U.S. stock market

This paper proposes a new empirical testing method for detecting herding in stock markets. The traditional regression approach is extended to a vector autoregressive framework, in which the predictive power of squared index returns for the cross-sectional dispersion of equity returns is tested using a Granger causality test. Macroeconomic news announcements and the aggregate number of firm-level news items are treated as conditioning variables, while the average sentiment of firm-level news is treated as jointly determined. The testing algorithm allows the change points in the causal relationships between the cross-sectional dispersion of returns and squared index returns to be determined endogenously rather than being chosen arbitrarily a priori. Evidence of herding is detected in the constituent stocks of the Dow Jones Industrial Average at the onset of the subprime mortgage crisis, during the European debt and the U.S. debt-ceiling crises and the Chinese stock market crash of 2015. These results contrast with those obtained from the traditional methods where little evidence of herding is found in the US stock market.
